Find the missing number?

A. 2

B. 7

C. 0

D. 4

Answer: Option A

Solution(By Examveda Team)

Start with the top left hand box, and move around the others in a clockwise spiral towards the centre.
Read each box as a pair of 2 digit numbers, one above the other. The sum of the 2 digit numbers in each box follows the sequence 55, 60, 65, 70 and 75. So,

43 + 3X = 75
3X = 32 Thus,
X = 2
Missing number = 2
